DNS Records Management for Sites

DNS Records Management

Overview​

VNIS provides centralized DNS records management capabilities for each site on the system. Each DNS record corresponds to a FQDN (Fully Qualified Domain Name) - meaning a subdomain or complete domain. DNS records management helps you actively control, optimize, and protect the operation of domains, services, and applications.

VNIS DNS Architecture​

VNIS uses a global distributed DNS infrastructure based on the following technologies and design:

  • Anycast Network: The DNS system uses IP Anycast technology allowing user routing to the nearest DNS server, minimizing latency and increasing fault tolerance.
  • Zone Replication: Real-time zone data synchronization between nameservers with <10ms latency.
  • In-memory Query Caching: High-performance DNS query caching at each PoP (Point of Presence).
  • Recursive Resolvers: Recursive resolution with intelligent caching and prefetch capabilities.
  • DNSSEC Support: DNS data integrity protection with digital signatures.

Technical Specifications:​

  • Query Throughput: >100,000 queries/second per DNS server
  • Response Time: 20-40ms average globally
  • Availability: 99.999% (Five-9s) with active-active architecture and automatic failover
  • Security: DDoS protection with volumetric attack mitigation capabilities up to 2Tbps

Getting Started​

Quick Setup Guide​

  1. Add DNS Records - Create your first DNS entries
  2. Configure Load Balancing - Set up traffic distribution
  3. Enable Multi-CDN - Activate intelligent routing
  4. Monitor Performance - Track metrics and optimize configuration

Best Practices​

  • Use appropriate TTL values for your use case (lower for dynamic, higher for static)
  • Enable Multi-CDN for critical services requiring high availability
  • Implement health checks for multi-origin configurations
  • Regular monitoring and optimization of DNS performance
